Simple CLI reminder

Here is a simple one liner to aid you in remembering certain tasks you need to complete. This command will create a popup on screen (tested using Debian based distros) as a reminder to complete the job assigned;

In the command (echo “DISPLAY=$DISPLAY xmessage remember to reset account ips” | at 03:00) the message follows the xmessage command. The “remember to reset account ips” is where the message you wish to relate will appear.
The “at 03:00” will need to modified to fit the desired time frame in which the task is to be started.

The “at” can also be changed to reflect the number of hours in which the reminder is due, for example;

Date:
Format month, date, year
today – Indicates the current day.
tomorrow – Indicates the day following the current day

The response you should get if the command was successfully acepted is;
warning: commands will be executed using /bin/sh
job 1 at Sat Dec 12 22:30:00 2009

This reminder command can also be setup as a crontab to remind you of a daily reoccurring event. You will need to put the reminder in a file and chmod+x the file in order to make it executable so crontab can run it.
